Tax Reconciliation and Capital Gains Taxes
A Supply-Side Blueprint for Broadening the Capital Base, Alleviating Housing Lock-In, and Lowering Marginal Rates
Key Findings:
This proposal optimizes federal revenue generation and accelerates economic growth by combining lower marginal tax rates on capital gains with a broader capital gains tax base. By reducing transaction penalties while systematically closing structural loopholes, this framework unlocks stagnant capital and ensures long-term fiscal solvency.
· Targeted Capital Gains Compression: Lowers the top statutory rates to 12.5 percent and 17.5 percent to unlock “locked-in” assets, lower the cost of capital, and immediately boost market liquidity.
· Surtax Realignment: Increases the Net Investment Income Tax (NIIT) to a flat 6.0 percent to preserve progressivity among high-income earners and offset initial rate reductions.
· Housing Market Integration: Uniformly applies the new rates to real property to eliminate tax arbitrage and dismantle the “lock-in effect,” freeing stagnant residential inventory for older homeowners and expanding supply.
· Repeal of Section 1031 Exchanges: Phases out like-kind real estate deferrals over five years to remove artificial distortions in asset allocation and permanently broaden the tax base.
· Modified Basis Adjustment at Death: Replaces complete step-up with a fractional 50 percent basis adjustment, deferring the tax liability until a voluntary sale occurs to eliminate estate-planning lock-in without forcing disruptive liquidity events.
· Programmatic Pre-Tax Asset Conversion: Implements an automated 5-year post-inheritance window for conventional retirement assets, shifting final balances from ordinary income schedules to capital gains rates to protect heirs from tax-bracket spikes while accelerating Treasury receipts.
· Taxation of Inherited Roth Vehicles: Automates the transition of inherited Roth funds into standard taxable brokerage portfolios after five years to integrate compounding growth back into the active tax base without assessing distribution penalties.
· Post-Mortem Excise Tax on “Mega-Roths”: Enacts a flat 5.0 percent levy on inherited Roth balances exceeding $10 million to cleanly capture extreme wealth insulated in tax shelters (the Peter Thiel exception) while actively encouraging unlimited lifetime capital accumulation below that threshold.
· Abolition of the Federal Estate Tax: Repeals the federal estate and gift tax regime entirely to eliminate double-taxation and protect family-owned businesses and farms from predatory, forced liquidations.
· Entitlement Solvency Integration: Introduces a 2.5 percent levy on capped capital gains contributions to fund Social Security, aligning the interests of entitlement advocates with supply-side proponents of lower tax rates.
Previous memos considered how the tax reconciliation bill could be used to facilitate health insurance reform and student debt reform. The primary focus of this article outlining a third-party tax reconciliation program involves improvements to capital gains tax rules.
Democrats strongly feel that the existence of a preferential tax rate on capital gains (a lower tax rate on capital gains than income) is unfair. Several problems with this argument exist:
· The decision to realize a capital gain is optional, and higher rates discourage capital gains realizations.
· Current law allows for complete step-up in basis at death, leading to the complete avoidance of capital gains taxes.
· The combination of higher capital gains tax rates and step-up in basis discourages sales by older homeowners with large gains, reducing the inventory of homes for sale.
· Some real estate investors avoid all capital gains taxes for business and investment purposes by putting properties into Section 1031 exchanges.
Introduction:
An alternative approach to capital gains taxation—one that lowers rates while broadening the tax base—can both increase federal revenue and stimulate economic growth. The approach towards lower rates and a broader tax base is guided by Arthur Laffer’s insight that a revenue-optimizing tax rate exists somewhere in the middle, never at the 0 percent or 100 percent endpoints. Just as higher ordinary income rates past the optimal point discourage work, higher capital gains rates past the optimal point drastically lower optional asset realizations. These alternative capital gains tax rules could also involve earmarking more funds from capital gains tax and net investment income tax receipts towards entitlement programs, offsetting or preventing projected insolvencies.
1. Restructuring of Long-Term Capital Gains Tax Rates
The proposal flattens the long-term capital gains and qualified dividends schedule by reducing the top two statutory rates by 2.5 percentage points, while maintaining the existing income brackets to preserve progressivity. The bottom tier is left untouched to protect lower-income savers.
The restructured schedule maps directly onto current statutory income thresholds:
· 0 Percent Bracket: Retained for low-income investors.
· 12.5 Percent Bracket: Replaces the current 15% rate, applying to the exact same income ranges.
· 17.5 Percent Bracket: Replaces the current 20% rate, applying to the exact same top-tier income cutoffs.
By directly lowering the transaction penalty on realizations, this targeted reduction lowers the cost of capital, unlocks “locked-in” assets, and immediately injects liquidity back into the broader market.
2. Expansion of the Net Investment Income Tax (NIIT)
To partially offset the revenue impacts of the capital gains tax reduction and ensure continued progressivity among high-income earners, the proposal increases the Net Investment Income Tax (NIIT) established under Internal Revenue Code Section 1411.
Rate Adjustment: The NIIT rate will be increased from its current statutory level of 3.8% to a new flat rate of 6.0%.
Threshold Retention: The tax will continue to apply to the lesser of net investment income or the excess of Modified Adjusted Gross Income (MAGI) over the existing statutory thresholds (currently set at $200,000 for single filers and $250,000 for married couples filing jointly).
3. Application of Unified Rates to Real Property and Market Liquidity
The newly proposed 12.5% and 17.5% long-term capital gains brackets apply uniformly to real estate, including principal residences, while leaving existing Section 121 statutory exclusions fully intact.
Maintaining a unified rate schedule prevents structural distortions and tax arbitrage. By lowering the top statutory rate to 17.5%, this policy directly facilitates transactions by long-tenured homeowners whose lifetime asset appreciation exceeds the standard $250,000/$500,000 single/married exclusion limits. (Note, proposal 10 includes a 2.5 percent trust fund levy, which if adopted, could apply to gains below the exemption thresholds.)
Reducing this transaction penalty expands active housing inventory, enables growing families to move up into larger homes, and removes a major tax barrier for older homeowners. Rather than remaining locked in a primary residence until death solely to secure a basis adjustment for heirs, seniors are economically empowered to downsize or relocate closer to family.
Crucially, while this proposal preserves the current zero percent tax tier for gains falling within the standard Section 121 statutory limits, this design choice represents a significant area for future policy optimization. Critics could reasonably argue that introducing a modest, low-baseline capital gains rate on all residential real estate transactions would generate substantial, predictable federal revenue while still entirely preserving geographic and social mobility.
4. Repeal of Section 1031 Like-Kind Exchanges and Rate Uniformity
To eliminate artificial distortions in capital allocation, this proposal advocates for the full repeal of Internal Revenue Code Section 1031, which currently permits real estate investors to defer capital gains tax indefinitely by rolling transaction proceeds into replacement properties.
There is no sound economic justification for maintaining a distinct or preferential tax rate for gains realized on investment real estate versus other capital assets.
To prevent an abrupt liquidity freeze in commercial real estate markets and to proactively generate significant short-term federal revenue, the repeal of Section 1031 will be phased in. There will be an immediate ban on the acquisition of new 1031 properties, the open-ended rolling over of basis is immediately terminated, only 50 percent of gains realized in the first five years after the enactment of the proposal will be subject to a capital gains tax, and 100 percent of realizations will be subject to tax from year 6 onwards.
5. Structural Reform of Basis Adjustment at Death and Mitigation of Capital Loss Penalties
The proposed change establishes a new cost basis automatically adjusted to a midpoint exactly halfway between the decedent’s historical cost basis and the fair market value.
Under current framework guidelines governed by Internal Revenue Code Section 1014, the tax basis of a capital asset held at death is adjusted to its fair market value on the date of the decedent’s passing. The complete elimination of basis at death creates an incentive for some households to maintain ownership of assets until death to reduce the tax liability of heirs. This provision can be especially onerous to older homeowners sitting on a large gain in their primary residence. They may prefer to downsize and move but this action could substantially reduce their legacy to their heirs.
For assets that have declined in value, the basis will similarly be adjusted to the midpoint between historical cost and fair market value. By preventing an absolute step-down, this provision preserves 50 percent of the embedded capital loss, allowing heirs to utilize the remaining loss to offset future gains when the asset is sold.
To eliminate liquidity friction at death, no tax liability is triggered by the transfer itself. The tax is deferred entirely until the beneficiary chooses to liquidate the asset, at which point the gain or loss is recognized under the unified 12.5 percent and 17.5 percent statutory rate schedule.
Gains on the sale of a primary home will be reduced by an exemption equal to $250,000 so the new tax should not substantially reduce liquidity for people who sell an inherited home.
6. Structural Reframing and Capital Gains Reclassification of Inherited Traditional Retirement Assets
To accelerate capital velocity into liquid, productive market investments and eliminate multi-generational tax insulation, this paper proposes a standardized 5-year duration for tax-deferred inheritance structures (such as traditional IRAs and 401(k)s). Rather than utilizing punitive regulatory penalties or forcing mandatory liquidations that trigger destructive ordinary income tax spikes, this policy implements a seamless, non-coercive reclassification at the conclusion of the 5-year post-inheritance window.
· Five-Year Tax-Sheltered Horizon: Non-spouse beneficiaries retain the right to maintain inherited assets the traditional tax-deferred shell for up to five calendar years following the decedent’s passing.
· Programmatic Reclassification at Year 5: On December 31 of the fifth calendar year, the tax-deferred status of the account automatically expires. The account structures dissolve seamlessly, and the underlying securities are programmatically transitioned into standard taxable brokerage portfolios. No early withdrawal penalties or compliance fees are assessed.
· Application of Unified Capital Gains Rates: Upon this automatic conversion, the embedded growth is detached from ordinary income schedules. The cost basis of the securities is automatically adjusted to a midpoint exactly halfway between the decedent’s historical cost basis and the fair market value at the time of conversion. Moving forward, all subsequent liquidations face the paper’s unified 12.5 percent and 17.5 percent capital gains rate schedule.
By replacing extended tax-insulation windows with an automated 5-year transition, this framework achieves clean, predictable revenue realization for the Treasury while providing a smooth, friction-free path for heirs to integrate inherited wealth into the standard market.
Macroeconomic and Revenue Impact Analysis: While compressing the inheritance window from 10 years to 5 years accelerates the transition of assets, this programmatic framework functions as an optimized, pro-taxpayer mechanism that simultaneously raises structural federal revenue. Under current law, non-spouse heirs inheriting conventional, pre-tax retirement accounts face a severe structural penalty: because these accounts possess a zero-tax basis, all forced distributions are taxed as ordinary income. When heirs inherit these assets during their peak earning years, a massive year-10 liquidation stacks directly on top of their existing salary, creating a destructive tax bracket spike that can consume up to 37 percent of the wealth. By fundamentally shifting these assets away from ordinary income schedules and onto the paper’s unified 12.5 percent and 17.5 percent capital gains brackets—while providing a 50 percent basis step-up at conversion—this policy fundamentally defuses that ordinary income tax liability.
From a public finance perspective, this provision serves as a highly efficient revenue accelerator. Pulling the automatic conversion window forward by five full years captures substantial revenue for the Treasury significantly faster, maximizing the time-value of collection. Furthermore, because the underlying securities are programmatically transitioned into standard taxable brokerage portfolios rather than being liquidated under duress, they are permanently integrated into the active tax base. Moving forward, all subsequent dividend payments, realized gains, and compounding growth generate annual tax revenue, subject to the unified capital gains rates and the updated 6.0 percent Net Investment Income Tax (NIIT). This accelerates capital velocity, broadens the permanent tax base, and yields predictable, elevated revenue realizations that far outpace the current, uncoordinated 10-year deferral system.
7. Implementation of a 5-Year Structural Transition for Inherited Roth Assets
Current statutory rules allow non-spouse beneficiaries to hoard assets inside an inherited Roth IRA for up to ten years completely tax-free, with no annual distribution mandates. To optimize public finance outcomes and accelerate capital integration, this paper replaces the uncoordinated 10-year liquidation rule with a uniform 5-year operational boundary, converting inherited Roth vehicles into standard taxable assets without forcing disruptive liquidations or assessment penalties.
The 5-Year Automatic Conversion: The inherited Roth vehicle retains complete tax-free growth status for exactly five calendar years following the owner’s death. On December 31 of the fifth calendar year, the tax-exempt status of the account expires automatically. No forced asset liquidations, withdrawal mandates, or compliance penalties are triggered.
Existing rules governing Roth IRAs rely on penalties for undistributed funds after 10 years. I have a strong aversion to penalizing taxpayers in this manner. This policy simply automatically converts undistributed Roth funds to taxable assets five years after they are inherited.
To establish an equitable baseline, the assets receive a clean step-up to their fair market value on the date of conversion. Moving forward, all subsequent capital appreciation or dividend growth generated by these assets is fully integrated into the tax base, subject to the unified 12.5 percent and 17.5 percent capital gains rates, alongside the updated 6.0 percent Net Investment Income Tax where applicable.
This video details how the IRS manages current inheritance windows and the complexities that beneficiaries face under the existing 10-year rule, highlighting the exact baseline compliance hurdles that your 5-year automatic conversion model eliminates.
8. Implementation of a High-Balance Post-Mortem Excise Tax on “Mega-Roth” Structures
This paper proposes a flat 5.0 percent Post-Mortem Excise Tax on the aggregate fair market value of all inherited Roth IRA and Roth 401(k) accounts exceeding an absolute baseline threshold of $10 million on the date of the decedent’s passing.
· Complete Insulation for Standard Savers: Every dollar of accumulated Roth wealth below the $10 million ceiling remains entirely exempt from this levy, fully shielding standard savers who utilized the accounts under standard statutory contribution limits.
· Preservation of Lifetime Accumulation Incentives: A 5.0 percent tax rate is mathematically negligible relative to the compounding benefits of a tax-exempt vehicle over several decades. Because the rate is so low, it exerts zero downward pressure on an entrepreneur’s or investor’s desire to maximize growth. The explicit objective of this policy is to actively encourage savers to accumulate as much capital as possible their Roth vehicles. The levy functions as a modest back-end equalization mechanism at the end of a lifecycle, rather than a punitive barrier during it.
· Administrative Liquidity: The 5.0 percent excise tax is assessed at the account level and paid directly out of the mega-Roth assets before the remainder of the balance undergoes the programmatic 5-year transition into standard taxable brokerage portfolios outlined in Section 7.
Policy Motivation and Distinctions
Under current regulatory frameworks, unique asset positioning—such as placing founders’ private equity shares, start-up options, or highly discounted assets inside a Roth shell—has permitted select individuals to accumulate “mega-Roth” balances stretching into the billions of dollars. A prominent public example of this structural breakdown is tech investor Peter Thiel, who famously amassed a multi-billion-dollar Roth IRA using early-stage startup shares. Because these structures completely insulate explosive lifetime wealth creation from both ordinary income and capital gains schedules indefinitely, they operate as unintended, permanent federal tax havens.
It is critical to note that this framework does not exclusively target Peter Thiel or any single individual, nor does it adopt the friction-heavy mechanisms previously proposed by Congress. Past drafts of the 2021 Build Back Better Act attempted to target these accounts aggressively by capping total IRA contributions at $10 million and forcing massive, immediate lifetime distributions of 50% to 100% on excess balances for high earners. Those previous designs created severe distortions: they required invasive, ongoing annual valuations of private assets, disrupted active capital compounding during the owner’s lifetime, and penalized high-wealth accumulation itself.
By shifting the mechanism entirely to a low-rate, post-mortem excise tax, this framework successfully captures a fair slice of lifetime capital accumulation that completely escaped the standard tax loop, generates immediate federal revenue from previously unreachable tax shelters, and maintains the integrity of broader capital markets—all while keeping the psychological incentive to build substantial private wealth fully intact.
9. Complete Elimination of the Federal Estate and Gift Tax Regime
This paper proposes the total repeal of the Federal Estate Tax, Generation-Skipping Transfer Tax, and Gift Tax (Chapter 11, 12, and 13 of the Internal Revenue Code).
· Harmonization with the New Tax Base: Under the unified framework established in this bill, the transfer of wealth at death is already fundamentally reordered through partial step-up in basis (Section 6) and the 5.0 percent mega-Roth post-mortem excise tax (Section 8). Maintaining a separate estate tax layer constitutes uncoordinated double-taxation.
· Elimination of Forced Liquidity Events: By abolishing the estate tax, the federal government completely removes the threat of forced, predatory liquidations of family-owned businesses, agricultural land, and illiquid private enterprises.
· Eradication of the Wealth-Destructive Avoidance Industry: Repealing the estate tax dismantles a massive, economically dead-weight compliance industry dedicated to constructing complex trusts, valuation discounts, and artificial holding companies designed solely to bypass asset-transfer penalties.
Policy Motivation and Economic Rationale
The traditional federal estate tax is an obsolete, friction-heavy revenue instrument. While conceptually designed to limit dynastic wealth concentration, in practice, it operates primarily as a tax on the illiquid and the poorly advised. Ultra-high-net-worth families routinely utilize sophisticated legal structures to shelter billions in liquid wealth, while mid-tier entrepreneurs and multi-generational family business owners are frequently hit with massive, unexpected tax bills that force the dissolution of productive firms. Furthermore, the estate tax raises a negligible fraction of federal revenues while imposing massive systemic compliance costs.
By pairing the total repeal of the estate tax with the dynamic baseline reforms introduced earlier in this paper, we achieve a far more equitable and efficient economic equilibrium. Rather than assessing a massive, punitive tax on an arbitrary date (death) based on subjective, easily manipulated asset valuations, the tax code under this framework shifts entirely to a realization-based and liquidity-aware model.
Standard inherited assets retain their underlying tax exposure through modified basis carryover, meaning the tax is only paid when the heir voluntarily chooses to sell the asset in an orderly, market-driven transaction. Meanwhile, the uniquely insulated tax-haven properties of ultra-high-balance Roth accounts are cleanly accounted for via the non-disruptive 5.0 percent post-mortem levy. Sweeping away the estate tax removes a major psychological barrier to lifetime domestic capital investment, simplifies the tax code, and ensures that federal revenue generation tracks actual economic transactions rather than arbitrary lifecycle events.
10. Creation of a 2.5% Tax Subject to a Ceiling for Contributions to Social Security
The preceding seven proposals were designed to increase capital gains realizations to increase revenue and expand economic growth. This proposal allocates a new 2.5% tax subject with fees provided to the Social Security Trust fund.
To maintain the historical and legal design of Social Security as a contributory social insurance program rather than a general welfare surcharge, this levy must be tied to future benefit calculations.
To achieve this integration, policymakers could choose between two primary structural approaches:
· The Parallel Factor Approach: The policy introduces an Average Indexed Capital Earnings (AICE) factor into the standard Social Security administration framework, acting as a parallel calculation to the traditional wage-based Average Indexed Monthly Earnings (AIME) formula.
· The Direct Integration Approach: Alternatively, capital gains subject to the levy could be blended directly into the existing AIME formula alongside traditional wage earnings.
Regardless of the path chosen, implementing this policy introduces a distinct structural challenge that must be resolved by Social Security Administration actuaries. Because asset realizations are inherently volatile and “lumpy” compared to steady lifetime wages, a single large liquidation could artificially distort a taxpayer’s 35-year earnings history or crowd out years of legitimate wage contributions. Actuaries will need to design an appropriate smoothing mechanism—such as a multi-year rolling average or a modified indexation formula—to ensure these capital contributions scale the Primary Insurance Amount (PIA) in an actuarially sound, equitable manner.
The 2.5 percent levy would apply uniformly to all long-term capital gains and qualified dividends recognized within the newly established 12.5 percent and 17.5 percent statutory brackets and to gains on principal residences below the $250,000/$500,000 exemption.
The total volume of capital gains subject to this levy is capped at $50,000 per year, yielding a maximum annual Trust Fund contribution of $1,250 per taxpayer.
By embedding this 2.5 percent payroll tax directly inside the OASI funding stream, any future legislative effort to increase the baseline capital gains rate introduces an immediate, quantifiable threat to Social Security solvency because higher rates lower realizations and reduce contributions to the Trust fund. In fact, advocates concerned strictly about Trust Fund Solvency and retirement income could favor further reductions in capital gains taxes which would increase realizations and new Social Security contributions.
This architecture improves the solvency of the Trust fund, expands retirement benefits for people who realize gains, and aligns the interest of entitlement advocates with the interests of people favoring lower capital gains tax rates.
Conclusion
The ten policy proposals outlined in this memo represent a cohesive framework, but they are by no means the only configurations possible. Future iterations of this program could explore different permutations of these ideas—such as adjusting the phase-in timeline for the Section 1031 repeal, altering the specific percentage split for basis adjustments at death, or modifying the annual cap on capital gains subject to the Social Security levy. Because tweaking these variables can significantly alter macroeconomic outcomes, it is vital to establish a process that moves away from rigid ideological battlelines. Instead, modifications to these proposals must be guided by a rigorous, objective cost-benefit analysis. This process should actively seek out and integrate input from individuals with diverse perspectives, ensuring that the final legislative package is stress-tested against real-world economic conditions rather than political dogmas.
Central to evaluating any modification is a two-sided principle rooted in the insights of Arthur Laffer. While historically applied to ordinary income tax, the Laffer Curve logic applies acutely to capital gains taxation because realizations are entirely optional; when tax rates are too high, investors simply lock in their assets, freezing market liquidity and starving the Treasury. There is an undeniable optimum rate for revenue generation—it is demonstrably not 100 percent, but crucially, it is also not 0 percent. Recognizing that this optimum lies between these two extremes is what guides the balanced reforms suggested for Section 1031 exchanges and the eventual taxation of inherited Roth IRAs. By capturing revenue at an optimized threshold without completely erasing the incentive to invest, the government can maximize public finance health while sustaining economic velocity.
Ultimately, reforming capital gains is not just a theoretical math exercise; it has a profound, real-world impact on broader economic growth and major societal pain points. This is especially true in the residential housing market, where the current tax code forces an artificial freeze on inventory. When an elderly homeowner faces a massive tax penalty for downsizing or moving closer to family, they choose to stay put to preserve a full step-up in basis at death. This lock-in effect starves the market of entry-level housing supply, which is a vital driver of macroeconomic expansion. Furthermore, it adds unnecessary financial friction to incredibly difficult, emotional end-of-life housing decisions—including transitions into assisted living or managing long-term care spend-down rules. A truly complete tax reconciliation framework must recognize these intersecting pressures, ensuring that capital gains rules unlock market velocity rather than penalizing families during critical life transitions.
